The two substrates of this enzyme are D-mannonic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are D-fructuronic acid (shown in its keto form), reduced NADH, and a proton.[1][2][3]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is D-mannonate:NAD+ 5-oxidoreductase. Other names in common use include mannonate oxidoreductase, mannonic dehydrogenase, D-mannonate dehydrogenase, and D-mannonate:NAD+ oxidoreductase. This enzyme participates in pentose and glucuronate interconversions.
